Afamelanotide
Afamelanotide is a synthetic 13-amino-acid analogue of alpha-MSH with norleucine at position 4 and D-phenylalanine at position 7, first reported in 1980 as a highly potent, long-acting melanotropin. It was developed clinically as a subcutaneous implant for erythropoietic protoporphyria.
